Abstract:
Objective:To explore the significance of multiple detector spiral CT multi-phase enhanced scan in differentiating liver tumors.Methods: A total of 141 patients, during from March 2011 to May 2015 in our hospital, pathologically diagnosed as liver tumors were selected to undergo multiple detector spiral CT multi-phase enhanced scan. The different performances and results in CT plain and enhanced scan for diagnosing liver cancer were observed and the sensitivity of CT multi-phase enhanced scan was analyzed.Results: 93 cases were found in CT plain scan; 141 cases were found in the arterial phase, 112 cases were found in portal venous phase and 108 cases were found in extension period in CT multi-phase enhanced scan. The lesion detection rate of CT plain scan was significantly lower than whichever of CT multi-phase enhanced scan(P<0.05); under CT multi-phase enhanced scan, the majority of lesions were typical imaging and could be diagnosed. Using CT multi-phase enhanced scan, the sensitivity of hemangiomas was 88.9%, abscess was 71.4%, focal nodular hyperplasia was 83.3%, primary liver cancer was 81.6%, and liver metastases was 97.8%; the total accuracy was 88.7%.Conclusion: The multiple detector spiral CT multi-phase enhanced scan can accurately identify liver tumor lesion stages, and it can contribute to further clinical treatment.
